Is it possible to connect these two shields to my Arduino Uno? After a research on the internet, I discovered that they use some of the same pins. Even so, is it still possible for me to connect the LcdKeypad and the ArduinoWifi on my Arduino Uno? (the LCD would be on top)
Here are the pic of the shields, and some information:
WiFi shield info:
The Arduino communicates with the processor WiFi shield with the microSD card by SPI (Eurotherm the ICSP bus) that is on pins 11, 12 and 13 at Uno. The pin 10 is used to select the HDG104 and pin 4 to the microSD card(i dont need the pin 4 cause i wont use SD). These pins can not be used for input and output. The digital pin 7 is used for initialization of the communication protocol between the shield and Arduino WiFi and should not be used.
This shield we will have to use the following sequence to initialize the library LiquidCrystal: LiquidCrystal lcd (8,9,4,5,6,7);
As you guys have noticed, there is the pin 7 on both shields that I need to use. How would it work? Can I do this? If i can't, is there any solution that I can expand my pins that would not result buying a Mega?
I still have to connect two INFRA-RED sensors and a motor (using pins 0, 1, and 2). I don't know if i can connect on the pins TX and RX (they seem to work).
